Product Overview

 

 

Graphene oxide (GO) is a type of derivative in the process of graphite to graphene transformation, which is a layered material obtained by ultrasonic exfoliation, dispersion, and grinding after graphite oxidation. It was discovered by Oxford University chemist Benjamin Brodie in 1859.
Graphene oxide belongs to a two-dimensional structured nanomaterial with a single atomic layer thickness, composed of sp2 and sp3 hybridized carbon atoms. Its structure contains various oxygen-containing hydrophilic functional groups such as hydroxyl, carboxyl, and epoxy groups, and has good dispersibility in aqueous media.
The main methods for preparing graphene oxide include oxidation method, solvent exfoliation method, chemical vapor deposition method, micro mechanical exfoliation method, metal surface epitaxy method, etc. Among them, the most convenient, low-cost, and large-scale production method is oxidation method. The oxidation method can be divided into Staudenmaier method, Brodie method, Hummers method, Offering method, etc.
Due to its low preparation cost, good film-forming properties, large specific surface area, and easy functionalization, graphene oxide has broad application prospects in energy storage, batteries, photocatalysis, biomedical, sensors, water treatment, and other fields, and is widely used in modified polystyrene, polypropylene, polyurethane, polylactic acid, polymethyl methacrylate and other foaming materials.

Application Fields

 

Graphene oxide is a novel carbon material with excellent performance, rich in surface functional groups, and widely used in the following fields:
Electronic products: Many electronic devices can be manufactured using graphene oxide as a basic material for one of the components, and field-effect transistors using reduced graphene oxide have been used as chemical sensors and biosensors.
Energy Reserve: Nanocomposite materials that reduce graphene oxide have been used for high-capacity energy storage in lithium-ion batteries. Reduced graphene oxide with a large surface area can be used as an energy storage material in supercapacitors.
Biomedical: One application of graphene oxide in the biomedical field is as an element in drug delivery structures. Functionalized nano graphene oxide can be used for targeted distribution of anticancer drugs.
Biosensors: Graphene oxide, as a fluorescence quenching material, can be applied to biosensors with fluorescence resonance energy transfer effects.
Environmental protection: Graphene oxide based composite materials can be used to treat harmful gases and convert air pollutants into useful energy resources.


Product Features

 

The single-layer graphene oxide dispersion provided by Xianfeng Nano is prepared by ultrasonic dispersion of single-layer graphene oxide in a solvent. There are three specifications of sheet sizes: greater than 500nm, less than 500nm, and 50-200nm, which have the following characteristics:
1. Composed of single atomic layers: with an average thickness of 0.8-1.2nm and a monolayer rate of 99%.
2. Good dispersibility: Graphene oxide has good dispersibility in aqueous media, which makes it easier to mix with other materials in many applications.
3. Easy functionalization: Its surface contains various oxygen-containing functional groups, such as hydroxyl, carboxyl, and epoxy groups, which can be modified through chemical reactions to endow graphene oxide with new properties.
4. Multiple active sites: During the preparation process, a large number of active sites are generated, which is beneficial for interacting with other substances.
5. Special optical properties: Graphene oxide has a certain absorption in the visible light range, and its optical properties can be adjusted by changing its structure and functional groups.
6. Electrical properties: Although graphene oxide itself is an insulator, it can restore certain conductivity after reduction treatment, and its electrical properties can also be controlled through doping and other methods.

Pink pretty purse
Size: One Size, Color: Dragonfruit
Love this purse! So cute and fit my phone, wallet and lipgloss with room to spare. Can be dressed up or down. Very pretty color what you see is what you get. Packaged well and came in perfect condition. The coach quality is unmatched.

Beautiful bag BUT no hangtag💔
Size: One Size, Color: Merlot, Size: One Size, Color: Merlot
I was delighted with this bag! It’s my first time ordering Coach from Amazon. I saw it on sale and didn’t think twice. It came very well packaged, just like new. I attached the strap to wear it like shoulder strap and added a charm. 🍒✨ The problem?? It came without the Coach hangtag!! I was totally disappointed. I contacted Amazon of course, and they asked me to return the bag with no option to repurchase it at the same price I got it for. I highly doubt it will go on sale again, so I decided to keep it and managed to find the hangtag on Poshmark.

Coach Quality Never Fails
Size: One Size, Color: Black 1, Size: One Size, Color: Black 1
I'm not sure why there are any reviews complaining of silver hardware or size as that information is clearly listed in the product descriptions. One also needs to order directly from Coach and select the gift option to get the gift box and dust bag, which has always been the case. This Tabby is the perfect size to hold the contents of your wallet, your phone, and your keys. It's a clutch bag. The bag I received has silver hardware and full grain leather as advertised. It's a beautiful, quality bag and the difference between this and a fake is clear; the material feels durable and soft at the same time. The bag smells like leather. Ultimately, as I read and did my research, I'm very pleased with my purchase. I've dressed it up with a cheaper, smaller strap as I'm using this as an oversized wristlet at the moment; but I got everything I paid for.
